COIN-CONTROLLED LOCK.

Application filed July '7, 1923.

To all whom it may concern:

Be it known that we, EDWIN L. Enwanos, FRANK A. FARWELL, and FRANK O. TTLEY, citizens of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Coin-Controlled Lock, of which the following is a specification, reference being had to the accompanying drawings and to the letters and figures of reference marked thereon.

This invention relates to locking apparatus for doors of rooms or apartments, or toilet rooms, requiring entrance fees, the invention having reference more particularly to a door lock that is designed to be operated by means of a coin to unlock the door.

An object of the invention is to provide a simple and reliable coin-controlled lock suitable for use on doors, which shall be constructed of parts that may be manufactured at small cost.

Another object is to provide an improved coin-controlled locking apparatus which shall be of such construction as to permit of slight modifications as to details so as to be adapted to different conditions of operation, and which shall prevent operation of the look by improper means.

A further object is to provide an improved coincontrolled lock and coin box combined which shall be of such construction as to permit compactness of mechanism and provide for large coin capacity, which shall not have troublesome forms of springs, and which shall be durable and economical in use and not liable to become deranged nor troublesome in practical use.

lVith the above mentioned and other objects in view, the invention consists in a coin-controlled locking apparatus having operative mechanism of such design as to be readily operated and notgreatly retarded by frictional resistance which mechanism shall control the admission of coins and permit the coins to pass by the force of gravity through the lock controlling means and into the coin box; and, the invention consists also further in a novel locking bar and a novel coin chute, and in certain novel parts and combinations and arrangements of parts, as hereinafter particularly de- Serial No. 650,155.

scribed and further defined in the claims appended hereto.

Referring to the drawings,Figure 1 is a front elevation of the new coin-controlled lock arranged on the outer side of a door, a fragment of the door and its frame being shown; Fig. 2 is a fragmentary section ap proximately on the line II-II on Fig. 1, on an enlarged scale; Fig. 3 is a fragmentary edge view of the door and the improved lock applied thereto; Fig. 4 is an enlarged sectional elevation of the improved locking apparatus approximately on the line IV-IV in the Figure adjacent thereto; Fig. 5 is a transverse section approximately on the line VV in Fig. &, a portion being broken away; Fig. 6 is a fragmentary wow similar to the upper portion of Fig. 4-; but on a smaller scale and showing different parts in relatively different positions, the coin chute being in section; Fig. 7 is a hori- Zontal section approximately on the line VIIVII in Fig. 6 including a portion of the door; Fig. 8 is a fragmentary view showing portions of Fig. 4:, to illustrate the manner of preventing the entrance of a coin when one coin is already in the coin chute; Fig. 9 is a fragmentary view, as on the line IXIX in Fig. 8 showing particularly one side of the coin chute; Fig. 10 is a fragmentary sectional elevation similar to Fig. (3 but with the coin chute in a relatively different position, the section being on the line X-X in Fig. 7; Fig. 11 is a fragmentary view similar to Fig. 6 but with different parts in relatively different positions; Fig. 12 is a fragmentary horizontal section of the door and its frame and the top of the lock casing partially broken away to clearly show the connection of the lock bar and its keeper as preferably constructed Fig. 13 is a fragmentary sectional elevation on the line XX in Fig. 7; Fig. let is a fragmentary horizontal section of the door and its frame and the top of the lock casing partially broken away to illustrate a modified lock bar and keeper therefor; and, Fig. 15 is a fragmentary horizontal section of the door and its frame and the top of the look ing case, partially broken away to show another modified locking bar and keeper therefor adapted for an in-swinging door.

Throughout the different figures of the drawings similar reference characters indicate corresponding elements or features of construction herein referred-toin detail.

For descriptive purposes in the drawings a fragmentary door frame is shown; the numeral 1 indicates one side of the .frameito which the. door 2 is torbeilocked, and. the mimeral 1 indicates the opposite side of the door frame to which the door is connected by means of hinges 3. The coin-controlledlock as preferably constructedhas abaseplate or back wall 1 which is secured'by means of screws 5. to the outer side of the door; and constitutes a part of the'lock The upper portion of the base platelhas a 1 recess 6 in the rear portion thereof adjaoent to the door,,and the base plate has alsoarecess 7 adjacent to the edge ofthe door. The/lock casing includes a removable partwhich comprises a front plate 8, side plates 9; a-ndlO, a top plate 11 having-a lip,12 that extends into the recess 6, the top plate normally resting upon the top of. the base plate hand-a back plate 13 fixed to the'lower portion ofthe. side plates 9 and 10, the plate ,13fbe'ing secured directly to the doorjb y means of-screws 14:.

The top plate ll has a suitablyilocatedcoin slot 15 arranged transversely therein, and preferably also a guide hood 1'6to. receive a coin uprightly andguideit to the slot.

Locking mechanism comprises preferably a stub shaft 17v fixedto thehase plate adjacent to the lower portion thereof a d in proximity to the casingside10,,and va hub 18 is rotatively arranged on the shaft and has a counter-bore 19 in the outerendthereof receiving the head20 of a screw 21 inserted in the shaft andn'etainingv the hub on the shaft. An escutcheon plate and collar 22 is fixed on the front plate 8 and,rotativelysupports a spindle 23 having a transverse key projection 241-0n itsninner end thatis. removably inserted in slots 25' in the end of the wall of the hub 18, the outer end of the spindle having a handle 26 fixed thereon. A

novel movable coin chute is provided-Which i comprises a main plate-27 thatisfixed at its lower end to the hub 18 and extends upward, two sides28 andQQfiXeQd on themain plate, and a front plate 30 fixedto the sides to provide a chute of the required dimensions to permit the desired'cointo pass through it, the front plate extending, upward slightly beyond the sides and having ,a curved guide 31 fixed. thereon that projects inthe direction away fromthe mainplate and slightly downwardly, being arranged so asto becarried over thecoin slotbut-permitting a coin topass from the slot into the coin chute when the latter isin vertiealposition below the slot. The mainplate ofthe coin chute has a recess 32 inits edgethat is adjacent to the base platetthe side 28 being correspondingly cut away, and the plate 27 has a slot 33 extending downward from the top thereof. The front plate 30 has a slot 34; arranged opposite to theslot 33 and it has also a recess 35 corresponding "to the recess 32. The hub 18 has an arm 36 fixed thereon to which. a coil spring 37 of suitable Ilength is connected,.the-springbeing con nected. to :astu'd 38fi-Xedtothe base plate 4,

.the spring being strained to yleldingly hold the coin chute against a stop pin 39 secured to the base plate. The base plate has also anothergsto-p pin 39 to stop the movement of the coin chute when tilted over from the stop pin 39.

A novellockbar 4OIisprovided which is pivotally connected a-dj.acent vto one end thereof tothestub shaft 17 between thebase 3 plate stand the inner. endofthe hnbl8 and extends nearlyto the casingside :Qnvhiclris adjacent to' the edge! of ,the doom-and it-has an arm 41 fixed thereto that .extendskupwa-rdly from the, shaft. The ,uppeixend of ;the arm has a shoulder e2 to support .a coin in the upper portion of the chute, and thearm plate 4 and preferably extends partially across thetop o'f the armand the back of the coinchute. V r

An improved shutter isprovided which comprises a plate 45 .movably. arranged under the topplate 110 f the casing and preferably has a supporting fiange 46 by:

which itismountedon the=hase plate 4,;the flange having longitudinal slots 47 therein receiving retaining and. guiding screwed-8 which are screwed intojthe,base plate. The shutter is stopped initsmovements against the side. pla-tesr9 and;:10 ofthe casing. '.The

shutter plate 45 hasa'coin slot .49 inthe forward edge thereof that registers witht-he .slot 15 when the shutter is stoppedagainst the casing-side 9, to permit a coin to pass into the coin chute. The front portion of the shutter plate 45 has a downward eX- .tendmg arm 50 atasuitabledistance from the slot intheplateand it hasa-finger 51 j that extends towards thenpper portion of the coin .ohuteand may be received into the slots-.33 and34 being arranged-tobe engaged by a coin in the chuteto slide the shutter over so a as toclose the coin slot-15.

. The flange ofthe shutten has a stud 52 there .on whereby to move the shutter over topermit entrance of a coin-at proper times, An

elastic finger 53 is mountedas a tension spring on the base, plate .4 and extends aga nst. the; face of the flange 4E6 to slightly. retard movement of the shutter so that it may not he accidentally jja-rred from its proper position by slamming the door.

and extends across the recess.

The shutter plate has downward extending fingers 54 and 55 thereon to operate a registering counter.

A spindle 56 is rotatively arranged in the door and extends through the base plate 4 and also into an escutcheon plate 67 arranged on the inner side of the door, and it has a suitable handle 58 connected thereto in the escutcheon plate. The inner end of the spindle is supported in a. frame bracket 59 secured to the base plate 4. A lever is secured to the spindle and has an arm 60 extending upward and an arm 61 extending downward, the latter having a stud 62 fixed thereon. The upper arm 60 extends partially over the flange 46 and may be moved into engagement with the stud 52 to move the shutter to open position. The front plate 8 of the casing has a hollow cylindrical bearing 63 fixed thereto in which a key cylinder 64 is rotatively arranged, which being of conventional type requires no further description, and the inner end.

of the cylinder has an arm 65 fixed thereto that may be swung against the stud 62 whereby to move the lever arm 61 and cause operation of the arm 60. This enables the proprietor to unlock the door by means of a key without requiring the use of a coin.

A bracket 66 is secured to the base plate 4 and supports a suitable counter 67 that has an operating-shaft 68 which is provided with an arm 69 that extends between the fingers 54 and 55 to operate the counter in synchronism with the movement of the shutter. The side 9 of the casing has a window 70 through which to inspect the counter and ascertain the results of its operations.

The lower end of the lock casing being open, a coin box is removably inserted therein and comprises a. bottom 71, front and back plates 72 and 73 and side plates 74 and 75. A cross bar 76 is secured to the front and back plates 72 and 73 whereby to secure the coin box in place. A hollow bearing 77 is secured to the front plate 8 of the casing and has a key cylinder 78 rotatable therein, the key cylinder being adapted to be locked against rotation as is well known, and the rear end thereof has an arm 79 secured thereto which has a hook 8O thereon to engage the bar 76, the front plate 72 being suitably recessed to clear the bearing 77.

The edge. of the door has a recess 81 adjacent to the end of the lock bar and a guard plate 82 is secured to the edge of the door The inner side of the door preferably has a guard plate 83 secured thereto that extends across the recess and has an aperture 84 therein to receive a keeper 85 which has a base plate 86 that is secured to the inner side of the Y door frame part 1. The keeper has an incline-d end 87 to guide the lock bar up to the top of the keeper to permit the bar to fall by gravity into a notch 88 in the top of the keeper. Preferably a stop plate 89 is secured against the base plate 86 and supports a rubber buffer 90 against which the guard plate 83 may be directly stopped. The end of the lock bar and the keeper are effectually inclosed and can not be reached by an instrument in an attempt to improperly open the door.

In a slightly modified form a stop head 91 is secured to the inner side of the frame part- 1 and supports a rubber butter 92 and also a keeper below the butter, the keeper extending into and through the recess 81, the lock bar 40 having a relatively right angled projection 94 thereon that extends into the recess and engages the upper portion of the keeper, access thereto being prevented by the guard plate 82.

\Vhen the door 2 is designed to swing inward the lock bar 40 has a relatively right angled. extension 95 that extends through the recess 81 and has a relatively right angled extension 96 thereon that projects behind the frame part 1, being inclosed in a suitable box 97 that is secured to the inner side of the door and receiving a keeper 98 through a suitable opening in its forward side to be engaged by the extension 96, the keeper having abase plate 99 that is secured to the inner side of the part 1. In each case the keeper pro-per is similar to the notched keeper 85. The design is such as to permit the lock bar to fall by the force of gravity into the notch in the keeper, but obviously the lock bar could if desired be provided with an actuating spring. Also: the arm 60 could be provided with a spring to yieldingly hold it against the stop block 44 if desired.

In practical use, the mechanism being set as in Fig. 4, a coin 100 of standard dimensions is inserted through the coin slots 15 and 49 and gravitates into the coin chute until stopped upon the shoulder 42. It now the outer handle 26 is turned the coin is forced by the coin chute sidewise against the projection 43 and also against the finger 51, causing the arm 41 and the lock bar 40 to be tilted so that the bar is released from the keeper, the shutter being simultaneously shifted to close the coin slot 15, the shutter being stopped against the casing side 10 and retracts the operating arm 69 of the counter. Having released the lock bar from its keeper the door may be pulled open and the handle released. Upon release of the handle the lock bar drops to normal position, the coin chute and the arm 41 moves pivotally together, so that the coin is still supported upon the shoulder 42, letting the shutter rest against the casing side 10, thus preventing the insertion of another coin. The door having been opened by a person, the room or compartment may be entered, after which the door may be drawn shut or closed by means of its spring hinges, causing the lock bar to be automatically operated to lock the door in closed position. As the lock bar is forced up to the top of the keeper. thearm 4:1- is retracted and carries the shoulder 42 from beneath the coin, permitting the coin to fall into the coin box. When a person in the room or compartment desires to leave he turns the inner handle 58 which causes movement of the arms 60 and 61, the latter engaging the arm 41 and retracting the .lock

ar, while thearm-60 is broughtinto engagement with the stud 52, which causes the shutter to be moved over; to the casing side 9 soas to bring the slot 49 in the shutter below the slot: 15 the movement of the shut- .ter'causing operation of the counter. XVhen thus unlocked from tlierinside the door may be opened, after which the lock bar descends to normal position and is again operated to lock the door when thelatter is closed, without disturbing -other mechanism of the lock, thetapparatusbeing set again as in Fig. 4 to permit another operation by means of a coin.

In case the proprietor desires to open the doorwithout theuse of a coin and so as to not disturb the counter record, he inserts a special key in the key cylinder 64: and turns it so as to swing the arm 65 as indicated by broken lines inFig. 13, the arm engaging I the arm 41, and retracting the lock bar Without disturbing the coin chute and the shutter. Having operated the door it maybe again closed andlocked, the lock bar acting alone, and the door-may be operated-again from the inside by turning theinside handle as before to retract thelockbar.

lVhen the owner or proprietor desires to remove the coin from the .coin box, he inserts a key, in the key. cylinder 78 and; turns it so as to disconnect the hook 8.0 froin-t'he cross bar 76, permitting the coin box to descend from the casing. The coin boxis readily replaced to normal posit-ion and is again lockcd by swinging the arm 79- in the opposite direction so that-the hook 80 engages the lock bar 7.6. 7
